COUPLING FOR HOSE, STEAM-PIPE, 80c

SPECIFICATION forming part of Letters Patent No. 373,292, dated November 15, 1887.

Serial No. 240,874. No model.)

To aZZ whom it may concern: I

Be it known that we, PETER J AOOBSON and ALBERT BADE, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Couplings for Hose, Steam- Plpe, &c.; and we do hereby declare that the following is a full, clear, and exact description thereof.

Our invention relates to couplings for hose, steam-pipe,-&c., and will be fully described hereinafter.

In the drawings, Figure l is a longitudinal seotlon through the center of our improved coupling. Fig. 2 is a side elevation of the same,with the coupling-hook disengaged and the female portion partly in section; and Fig. 31s a section on line 3 3 of Fig. 1.

,Ais the male part of our coupling, which consists of a cylinder having a reduced portron to enter the female part, B, and a shoulder, a, on which'a conical collar, 0, is secured.

Behind the collar 0 and shoulder a a cam, D, having a handle, D, is fitted loosely, and held up against the shoulder a by a collar, b, that is riveted or brazed to the part A, and behind this collar b one end of the couplinghose E is securely fastened to the male por-. tion, while a similar male portion (not shown) is fastened to the other end of the couplinghose E.

The female part of our device consists of a cylinder similar to the cylinder A, but having a sufficient bore to admit the cylinder A, and carries two hooks, F, the shanks e of which are secured to it, preferably, by a band, G, and the points of which hooks project out beyond the end of the part B to enable the barbs f to ride over the collar 0 and engage its rear edge, as shown in Fig.1, when that portion of each hook between the barb and point will lie parallel to the beveled surfaces cl d of the longest portion of cam D.

The inner end of collar 0 projects slightly beyond the shoulder a, and is offset to form an annular recess, 0, for the end of part B,

and if found desirable this may contain a packing for making the joint steam-tight.

The long faces of cam D are beveled at d to an angle that about corresponds to that of the faces of the hooks F, the surface between part A from the'part B until the inclined surface of the collar 0 is between the two hooks, and the latter, by the elasticity of their shanks 0, will press upon said inclined surface of the to get out of order. The collar 0 may be either made separately from the cylinder A, and secured to, it'as shown, or, if preferred, formed with it.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a coupling for hose, steam-pipe, &c., the female part and its hooks that project be yond it, in combination with the male part and its conical collar and a disengaging-cam adapted for engagement with the faces of the hooks when turned to the right or left, as set forth.

2. In a coupling for hose, steam-pipe, &c., the combination of a male part haviuga'couical collar and a female part having projecting hooks for engagement with the collar, and a disengaging-cam having beveled surfaces for engagement with the faces of the hooks, all

constructed to operate substantially as de- PETER JACOBSON. ALBERT BADE.
